SELF-ADJUSTING BELT FOR COW-MILKERS.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application liled October 1,1907. Serial No. 395.440-

To all whom it may concern.

Be it known that l, FLoYn B. (inorr, a citizen of the United States, residing at St. Johnsville, in the county of M ontgomcry and State of New York, have invented certain new and useful Improvements in Self-Adjusting Belts for lllilkers, oi which the .l'ollowing is a specification.

My invention has relation to automatic milkers and self-adjusting belts, and consists of the novel construction and arrangement of the parts as set forth in this specification and the claims thereunto attached.

In the accompanying drawings, Figure 1, is a representation of a milch cow, with my invention adjusted in place. Fig. 2, is an edge view of my belt, winding attachments, buckles, etc. Fig. 3,is a cross sectional view on the line ar :10, of F ig. 4. Fig. 4, is a perspective View of my Winding device, and parts of the belt. Fig. 5, is an. elevation, partly in section and partly in perspective of the milking device minus the pail. Fig. 6, is a top plan view of the plate, holding the lower parts of the universal joint-sockets. Fig. 7, is a sectional view of my winding device. Fig. 8, is a cross section of said winding device, on the line 1 11 of Fig. 7.- Fig. 9, is a cross sectional view of Fig. 7 on the line a 2.

Similar numerals refer to similar parts throughout the several views.

lndescribingmyinvention I read the drawings from left to right.

My invention is described as follows The numeral 1,rcpresents the milch cow; 2, represents my self-adjusting belt 3, is a brace-belt; 4, the winding device; 5, the milker, and 6 and 7 are pipes which lead to the pail S.

The numeral 9, represents the plate provided with loops 9 and perforations 10,- in which perforations are screwed the lower ends of the lower parts 11,01 the universal jointsockets 12; 13,represents the caps which form the upper part of saiduniversal joint-sockets. The two loops 9, extending from the periphery of plate 9, one immediately opposite the other are for the purpose of receiving the hook ends of my self-adjusting belt. In these universal j oint-sockets work the bulbed ends of the extensions 14, and to the threaded ends of said extensions 14, are screwed the lower ends of con lings 15. These couplings are provided with glass tubes 16, and with openings 17, to enable the operator to see if the milk is coming down.

-to the left of said. belts 27 and 27,

In the upper end of said couplers 15, are screwed the lower ends ot the cups 1%. There are usually four cups used, but In the drawing only three are shown.

Attached to the lower face of the plate 9, is a cup 19, to the lower end of which is secured the necessary pipes which carry the milk to the pail. These pipes are provided with the necessary joints 20, that they may be turned in any direction.

My self-adjusting belt consists of a cylinder 21, having end pieces secured in lace by tie-rods 22 and. 23, and nuts 23. he purpose of said nuts is to allow the end pieces to be easily and readily removed, so that the internal )arts of said winding device may be cleaned and repaired. Journaled longitudinally in the center of said cylinder is an axle 24, and rigidly secured on said axle is a drum 25, and working around said axle is a roller 26. Secured to said drum is one end 0'1 a belt 27, wound around said drum several times, and its free end is passed over a roller 26, workin r around said tie-rod 23 and out through a ongitudinal slot 28, in the lower part of said cylinder. Immediately above said tie-rod 23, is secured a similar tie-rod 22, and immediately above said tierod 22, is a longitudinal slot 29, and secured to said tierod 23, is one end of a belt 27, its other end passing up through said slot 29. Immediately and encircling said drum, is a perforated disk 30 provided with notches 3] and 32 for the accommodation of said tie-rods. To the left 01'' said circular plate is a spring 33, which has one end secured. to said drum, and its other to the upper tierod 22. This spring is wound around said drum in a direction 0 posite to said belt,- so that when said be t is pulled on, the said spring is wound up, and when the belt is loosened, the spring unwinds. Said belt 27, passes upwardly, out of slot 29, and over the back of the cow, and

has attached toits opposite end a winding device 4, exactly siml ar to the one just described, and depending from the last-mentioned winding device is a belt 27, exactly similar to the belt 27 mentioned above. To the lower end of each of these last-mentioned belts 27, is secured a buckle 34. Secured in each of these buckles is a strap 35, and secured to the lower end of each of these stra s is a hook 36. This combination, the hoo s 36, the straps 35, buckles 34, belts 27, winding devices 4, and belt 27, constitute my self-adjusting belt. This belt is passed over the back of the cow with a winding device on each side, the lower ends extending downwardly and hooked in the loops 9, of the plate 9. Extending from the milker 5, forwardly, is another belt 3, to steady said milker, but this belt 3, I do not claim as a part of my invention.

The buckles 34, enable me to fit my belt to any sized cow, and as the cow breathes, thewinding device gradually allows the belt to contract and expand, and as the milk is drawn from the udder the belt contracts and keeps the mouths of the cups drawn up against the udder, and where a winding dev1ce is on each side of the cow, this contraction and expansion movement is not confined to one side of the cow, but operates equally on both sides, yet it is not absolutely necessary that a winding device be on both sides of the cow; one winding device will give reasonably satisfactory results.

Although I have specifically described the combination, construction and arrangement of the several parts of my invention I do not confine myself particularly to such specific combination, construction and arrangement, as I claim the right to make such changes and modification therein as may clearly fall within the scope of my invention, and which may be resorted to without departing from the spirit, or sacrificing any of my patentable rights therein.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination of the upper belt 27 winding devices 4, one secured to each end of said belt; lower belts 27, secured to the lower part of said winding devices; buckles 34, one secured to the lower end of each of said belts 27; straps 35, securedin said buckles; hook 36, secured to the lower ends'of saidstraps; loops 9, and perforatedplate 9, secured between said loops, said plate hold-. ing the cups, connections, and pipes that secured on said axle; a belt 27, having one,

end secured to said drum, its other end pass "ing down over the roller 26, and through said lower slot; a spring 33, having one end secured to said drum and the otherto the corresponding end. of said tie-rod 22, passin thence up through said upper slot of sai cylinder; a perforated dis provided with notches 31 and 32, situated at the left of said belts and encircling said drum; buckles 34, secured to the free ends of belts 27 and 27 straps 35, secured to said buckles, and hooks 36, secured to the lower ends of said straps, said hooks adapted to hook in the 100 s 9 of the perforated plate 9, substantia y as shown and described and for the purposes set forth.

3. A self-adjusting belt, consistin of a strap adapted to pass over the bac of a milch cow; winding members, one situated on each side of the cow and secured to each end of said stra stra s, each havin one end secured to t e win ing member 01 said .winding device, passing down through the lower part thereof and over a roller; lower straps adjustably. secured to the lower ends of said last-mentioned straps, and hooks secured, to the free ends of said lower straps, said hooks adapted to be secured in the loops of a erforated plate, substantially as shown and escribed'and for the purposes set forth. In testimony whereof I affix my signature in presence of two witnesses.
